The Lytro Has Landed

XConomy’s Wade Roush likewise has an interesting mix of great praise and faint damnation for the product. He predicts that Ren Ng, Lytro’s CEO, will “wind up in the history books alongside photographic pioneers like Mathew Brady, Eadweard Muybridge, Harold ‘Doc’ Edgerton, Edwin Land, and George Smith and Willard Boyle.” At the same time, though, he contests some of Ng’s claims about just how disruptive the device will be, declaring “the company will need to keep tinkering with the product before it has a real hit on its hands.”

Epson Moverio BT-100 review

Forget virtual reality; Epson’s newest innovation – on sale now in Japan, and destined for the UK early in 2012 – is designed to create a portable, transparent home cinema experience for bored business travellers, though there’s more to it than mere movies.

Armed with a Wi-Fi connection, the Moverio BT-100 can get online, and though it’s not possible to download apps and games, its browser does support Adobe Flash video (as well as MPEG and H-264 videos manually transferred via a PC).

The BT-100 runs an Android operating system. Version 2.2, to be exact, though it’s customised so much that it will be unfamiliar to most. It is controlled using a touch sensitive trackpad, which also houses a 4GB SD card to go with the internal 1GB of memory.

Battery life is rated at about six hours, and the product ships with a neat black carry case (though the whole package is rather large).

DIY Kit Overclocks Your Brain With Direct Current

Air Force researchers were delighted recently to learn that they could cut [the time required to train drone pilots] in half by delivering a mild electrical current (two milliamperes of direct current for 30 minutes) to pilot’s brains during training sessions on video simulators. There is also evidence that tCDS can induce the state of creative nirvana known as “flow.”

A Machine That Sniffs Out Cancer

A few years ago researchers in California received widespread attention for showing that dogs can smell cancer on a human’s breath. With 99 percent accuracy the canines could detect if a person had lung or breast cancer, beating the best figures from standard laboratory tests. Subsequent studies confirmed the results and provided further evidence that dogs really are man’s best friend.

The problem with cancer-detecting dogs is that, well, they’re dogs. Hospitals haven’t embraced the idea of a diagnostic tool that poops, barks, and requires feeding. With such concerns in mind, technology startups have hustled to build digital devices that can mimic the dogs’ olfactory sense and reduce the need for biopsies and CAT scans. Metabolomx, a 12-person outfit in Mountain View, Calif., now appears on the fast track—insofar as such a thing exists in the heavily regulated medical field—to bringing a cancer-sniffing device to market.

Visual Computing Still Decades from Computational Apex

With a resolution of about 30 megapixels, the human eye is able to gather information at about 72 frames per second which explains why many gamers debate the need for frame rates higher than 70 in games at all. One area that Sweeney did not touch on that I feel is worth mentioning is the brain’s ability to recognize patterns; or more precisely, changes in them. When you hear the term “stuttering” or “microstutter” on forums this is what gamers are perceiving. While a game could run at 80 FPS consistently, if the frame rate varies suddenly from 90 FPS to 80 FPS then a gamer may “feel” that difference though it doesn’t show up in traditional frame rate measurements.

In terms of the raw resolution though, Sweeney then posits that the maximum required resolution for the human eye to reach its apex in visual fidelity is 2560×1600 with a 30 degree field of view or 8000×4000 with a 90 degree FOV. That 2560×1600 resolution is what we see today on modern 30-in LCD panels but the 8000×4000 resolutions is about 16x that of current HDTVs.

Acer announces K520 laser-based light projector

[CeBIT 2012] At CeBIT 2012, Acer announced a new projector the K520 which uses laser instead of a regular projector lamp to display images. The K520 Hybrid LED Laser projector is said to deliver a dynamic contrast ratio of up to 100,000:1, 2000 lumens of brightness, 3D image output support, and features VGA, composite video/audio, and HDMI ports. It has a maximum output resolution of 1024 x 768 but supports 720p and 1080p input signals.

In case you’re wondering what the benefits of using laser over regular projector lamps are (no, you can’t cut through objects with these lasers), they last much longer than regular projector lamps. LED lasers can provide 20,000 hours of usage versus the 3,000 hours from regular projector lamps.
